Semantic Retrieval
Semantic retrieval is retrieval designed to match the intended meaning and relationships in a request rather than relying only on literal token overlap.
What it means
Implementations may use query expansion, entities, learned sparse or dense representations, knowledge structures or semantic reranking. The label states a goal and capability; it does not identify one algorithm.
Why it matters
Meaning-oriented matching can connect paraphrases and multilingual or conceptually related expressions. It can also overgeneralise, so evaluation needs difficult negatives and exact constraints.
Example
A request for `cancel my annual plan` can retrieve a subscription-termination policy even when the page uses `end membership`, while excluding unrelated account deletion.
Common mistakes
Do not call every vector lookup semantic retrieval, treat a product's semantic ranker as the initial retriever or ignore exact names and numbers. Preserve lexical and structured constraints where required.
How AYSA handles this
Signals reviewed
paraphrase tests, hard negatives, exact constraints, returned sources, locale
Problem AYSA can identify
AYSA can detect supplied results that match broad meaning but lose a required product, place or policy constraint.
Recommendation prepared
The proposal clarifies the source language or identifies a retrieval-side constraint for the system owner.
Approval preview
The user sees successful paraphrases, failed constraints, affected source and proposed action.
Execution
AYSA can improve approved source wording and structured evidence on supported WordPress pages.
Verification
AYSA recrawls the page and repeats connected semantic and exact-constraint test cases.
Limits
AYSA cannot guarantee that external systems interpret meaning consistently across models or languages.

Quick answers
Frequently asked questions
Is semantic retrieval always implemented with embeddings?
No. Embeddings are common, but expansion, entities, knowledge structures and learned reranking can also contribute.
